TPS53820: tps53820

Part Number: TPS53820

Hi,

I would like to know Is there any possibilities to change the output voltage value of TPS53820.

In the reference design it is 1V & 1.8V.

if  i would like to change to  1.2V & 1.8V  for my application, is it possible? if possible how?

Please help me to let know.

thanks

    Hi Adarsha, 

    The Vout can be programmed by I2C. 

    Can you let me the application information? How TPS53820 will be used in your application?

    Thanks

    Hi ,

    thanks for the reply.

    the application will be in the server board.

    I am looking for a replacement of dual output POL (IR3891 INFINEON) which is going to be EOL.

     With 12V input, I want to generate 1.2V(4A) & 1.8V(2A)  outputs to provide supply for  Microcontroller and FPGA and some other circuits.

    i have checked  TPS53820 datasheet and i could not find the programmable output voltage range ... it is 1V (PVCCANA) And 1.8V ... in reference design.

    my 1st preference is possibility  of configuring output Voltage without I2C interface.

    if not possible please let me know  the procedure with  i2c Interface programming and programmable output range.

    You can suggest Other parts from TI for the requirement without I2C interface.

    thanks and regards
